Hummer H3
Parts fit 2006 to 2010. Owner reports cover 1996 to 2025, mapped to 1 NHTSA name, so vehicles of very different ages are counted together.
19 of 257 parts name an engine. The other 159 fit any, so choosing one here only narrows those 19.
What owners report
6 of 12 components, the largest by share, together 64.2% of all mentions. 799 reports filed with NHTSA from 1996 to 2025, read through 5 name and year queries against 1 source name. A report can name more than one component, so these 799 reports carry 1,032 mentions, 1.29 for each report, and every share below is of those 1,032. 69 more mentions were filed as unknown or other and are excluded from both the rows and the total.
